I am trying to install an email server with dovecot and postfix using a MySQL database. I can send emails to other users of my domain @ eddelus.com and I can also receive emails from external domains, but I can not send emails to external domains.
I can connect using telnet to ports 110 and 587
Looking at the log (cat /var/log/mail.log) I find this:
